The arch system does not prepare a binary build it basically builds from source, it has depends=('qtwebkit' 'boost-libs')
makedepends=('cmake' 'gendesk' 'boost')
in the package file and there are no errors in building from source=("http://sigil.googlecode.com/files/Sigil-${pkgver}-Code.zip").

The error I get is at runtime but I have no idea what runtime dependency I am missing, should I have something from xerces?
